Trust may be an important part of agent's reasoning when resources, services or information are sought inside a multiagent system. Decision which agent to contact when more acceptable possibilities is naturally done with respect to expected outcome of forthcoming cooperation, so the partner with the best quality should be probably contacted first. Typically for one agent or device a trust may be evaluated in many contexts. Particular kinds of trust need not to be independent and trust in one aspect could influence trust in another aspect. We present a model of trusts as a multilevel computational graph where trusts are computed in conjunction on some trusts at preceding levels.
